A modern .NET framework for building feature-rich command-line interface (CLI) applications with minimal boilerplate.
CommandDotNet is a .NET framework for building modern command-line interface (CLI) applications. It provides out-of-the-box support for commands, sub-commands, validations, dependency injection, and many other features, reducing the complexity of CLI development. It solves the problem of writing repetitive boilerplate code for parsing arguments, routing commands, and generating help documentation.
.NET developers building CLI tools, utilities, or applications who want a robust, convention-based framework with minimal setup and extensive built-in features.
Developers choose CommandDotNet for its comprehensive feature set, adherence to POSIX conventions, and extensibility through middleware. Its integrated test tools and focus on modern CLI patterns make it a productive choice over manual parsing or less feature-rich alternatives.
A modern framework for building modern CLI apps
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automatically maps methods to commands with minimal boilerplate, as shown in the calculator example where basic methods become full CLI commands with auto-generated help.
Includes validation, type conversion, piping, and prompting out of the box, reducing the need for custom implementations for common CLI patterns.
Seamlessly works with .NET DI containers, enabling clean, testable command classes and modern application architecture without extra setup.
Provides utilities to test all CLI aspects, such as argument parsing and command routing, ensuring robustness without additional testing frameworks.
The project status admits low priority for new features, with maintainers focused on stability over innovation, which may leave gaps for emerging CLI trends.
While basic usage is straightforward, leveraging middleware and extensibility requires deeper understanding of the framework's architecture, increasing initial learning effort.
Compared to older frameworks like System.CommandLine, there are fewer community extensions and plugins, which can limit ready-made solutions for niche requirements.
